My 65 C-code has AC and a basic Retrosound radio, otherwise no added load on the electrical system, no plans to add any additional load on the electrical system. New AGM battery.
My alternator has D8ZF 40A stamped on the case.
How many amps does the alternator put out at idle?
At idle the lights flicker. I increased the idle speed to compensate. I dont have a tach, so no idea what the idle speed is.
Is this an alternator or wiring problem?
I have a new DC alternator harness that Im getting ready to install, but thought that I may as well replace the alternator while Im at it.
The car was "restored" in 05-ish, so everything is 14-ish years old.
Im also going to put the headlights on relays, I have them, just havent figured how where to hide them yet.
Am I better off upgrading to a 60 or 75 amp alternator, will a higher amperage alternator put out more amps at idle? At idle is the only issue Im having, otherwise the charging system is working properly.
